signor to The Beli Telephone Company of Canada, Montreal, Quebec, Canada, a corporation of Canada Fied Apr. 18, 1960, Ser. No. 22,817 5 Claims. (Cl. 248-74) This invention relates to a holding device and more particularly to a holding device adapted to be clamped on a supporting surface.

Numerous holding devices have been devised adapted to be clamped to a supporting surface. Such devices, however, require that the clamping surface be altered so that the device may be clamped thereon.

It is an object of this invention to provide a holding device suitable to be clamped to a supporting surface without the alteration or the marring of such surface.

Another object of this invention is to provide a holding device having the foregoing properties which is simple in structure, economical Ito manufacture and easily installed.

A further object of this invention is to provide a holding means having the foregoing properties capable f being adjusted to irregular supporting surfaces.

Another object of this invention is to provide a holding device having the foregoing characteristics arranged so that its overall dimensions may be adjusted.

These and other objects of this invention are attained by providing a plate member and a co-operating L-shaped member, the former member having slots through which fastening members extend to the latter so that the position of the members may be adjusted in relation to each other, together with a resilient member interposed between the two members so that :the holding device may be clamped to .the supporting surface of irregular shape.

A better understanding may be had by referring to the following description, taken in conjunction with the drawings, in which like numbers refer to like parts, in which:

FIGS. l and 2 illustrate a perspective view of the holding device, clamped in one assembly arrangement, to a flat surface;

FIGS. 3 and 4 illustrate perspective views of the holding device of this invention; and

FIG. 5 illustrates in section, the holding device, taken through 5 5 of FIG. 3.

Considering the drawings, there is shown a plate 1, having fastenings 2, 3 for securing to the plate 1 a desired element '17, provided with slotted openings 4, 5, through which the fastening members 6, 7 extend respectively, bearing surface adjusting screw 8, extending through the thread opening 12 and threaded openings 10', 11.

In co-operation with plate 1, is the L-shaped plate 9 having thread openings 10, 11 adapted to secure fasteners 6, 7, slotted openings 4', 5', and openings 13, 20 through Patented Oct. 31, 1951 ICC which an electrical conductor 19 may pass and recess 14 adapted to secure the end of screw 8.

There is also shown in the drawings, friction pads 15, 16 made of a resilient material adapted to hold the device securely to the supporting surface 18, adjusting itself to an irregular supporting surface which may exist.

In the installment of the holding device of the invention, an element, such as a connecting block, is fastened to the plate 1 by fasteners 2 and 3.

The elements 1 and 9 are clamped to the disc 18 by means of fasteners 6, 7 extending through plate 1 to the threaded openings 10, 11, the plates 1 and 9 being adjusted, by virtue of the slotted openings 4, 5, so that the pads 15, 16 only bear on the surface 18. The surfaces of the pads 15, 16 bearing on the surface 18 may be varied by the adjusting screw 8 which extends through the plate 1 and bears in the recess 14 of plate 9. A conductor 19 may be extended through openings 20, 13 to the block 17.

The assembly of the device as shown in FIG. 4, is the same as described heretofore for FIG. 3 except the fasteners 6, 7 extend through the slotted openings 4, 5 on the plate 1 to the threaded openings 10, 11 on plate 9.

What is claimed is:

1. A holding device adapted to be clamped on a supporting surface comprising in combination: a at plate member, an L-shaped plate member, the two elements being arranged such that, when assembled together the bottom face of the L-shaped member extends a predetermined distance below the bottom edge of the fiat plate member, and the top edge of the flat plate member extends a predetermined distance above the top edge of the L- shaped member, apertures and fastening means extending therethrough disposed at the bottom portion of that part of the members where their side faces oppose each other, apertures disposed in the said extended and horizontal portions of the L-shaped plate member.

2. A holding device in accordance with claim 1 in which the rst mentioned apertures are slotted.

3. A holding device in accordance with claim 2 having in combination therewith resilient elements disposed between the two members extending over the two opposing faces of the overlapping portions of the said members.

4. A holding device in accordance with claim 1 having in combination means to adjust the bearing surfaces of the two plates on the supporting surface.

5. A holding device in accordance with claim 4 in which said means comprises a threaded member extending through the iiat plate and bearing in a recess in L- shaped plate.
